ad9230的配置程序，差分输入输出，verilog(ad9230 configuration program, verilog)

基于FPGA的实现小数倍分频代码，广泛应用于数字通信中。-FPGA-based implementation of a small multiple of sub-frequency code, widely used in digital communications.

EDA技术及其应用《序列信号发生器的设计》，包括源文件。(EDA technology and its applications " sequence signal generator design, including source files.)

这篇是利用VHDL语言控制LCD1602芯片来显示时钟的简单代码。LCD1602顾名思义是一种02*16，即为两行十六列的液晶显示屏，液晶两行，每行可以显示16个字符，但是CGRAM及CGROM里面一共有160个字符，包括阿拉伯数字，英文字母大小写，常用符号及日文。每个字符对应于一个ASCII码值，在液晶显示屏上显示对应的字符时候，只需要将对应的ASCII码写到DDRAM中就好。

利用康芯公司的FPGA芯片设计制作频率计，实现对频率的测量。(Kang core using FPGA chip design company frequency meter, realize the frequency measurements.)

一个精确的到0.01s的时钟源程序，对于初学VHDL理解很有帮助，只给了源程序没有给出仿真波形-An accurate clock source to the 0.01s for the beginner to understand VHDL helpful not only to the simulation waveform of the source

显示频率测量，外接24MHz晶振，显示数据为三位，分四个档来测量-show frequency measurement, external 24MHz crystal oscillator, the data show that three, four hours to measure stalls
